How to change configurations or project structure or where LSP thinks project root is?

[DominikMendel]

Describe the bug
This is my first time using lsp-java so I apologize that this is more a question than a bug.
I have a project structure like this .../ProjectRoot and within ProjectRoot I have some sub-folders. /ProjectRoot/Project, /ProjectRoot/Apps, /ProjectRoot/Modules. The Project contains the necessary gradle files to build my project, but the Apps and Modules contain the Java files I need to edit and code with.

If I want to build my project from the command line this all works just fine

cd .../ProjectRoot/Project
~/./gradlew
~/./gradlew tasks
~/./gradlew assembleDebug

How can I configure lsp-java to see that is needs to build from /ProjectRoot/Project but also needs to link all the files from the other folders like /ProjectRoot/Apps, /ProjectRoot/Modules?
Any help would be greatly appreciated as I would love to do my dev work in Emacs.

Note
I am using this package out of the box with Doom Emacs.
I am also doing Android development, so there might be some hicups there. I am not expecting much though, I just want basic LSP Java features to work.

Use M-x lsp-workspace-folders-add/remove or I in the import project dialog. As a side note, AFAIK jdtls server does not work well with Android projects.

Thanks for the help, sadly I don't think that fixed my issue and it might be because of the whole Android project thing.
Do you have any recommendations or know of alternatives to use for Android?

There is netbeans server https://github.com/timfel/lsp-netbeans but I am not sure if it will work with Android projects too

@timfel might know.

I don't know about Android apps, but I do know the netbeans team has been focusing mostly on making gradle and micronaut work well recently. So you may be lucky the gradle support alone is good enough to understand the project structure
